Can polyacrylamide improve hydrocarbon production efficiency?

npj Materials Sustainability 2, Article number: 15 (2024) Cite this article Polyacrylamide (PAM) and its derivatives play a pivotal role in various facets of hydrocarbon development. Proper application and treatment of PAM have the potential to enhance hydrocarbon production efficiency while mitigating adverse environmental effects.

How are polyacrylamides treated?

The top left is the filter, the top right is the reservoir, and bottom left and bottom right are settling tanks. Polyacrylamides are typically addressed through various treatment methods, including membrane filtration, thermal distillation, oxidation treatment, and biological removal (Table 2).

Is polyacrylamide a good soil conditioner?

However, as these solutions are proposed, numerous doubts and opposing opinions are emerging. Polyacrylamide (PAM), also known as “soil conditioner”, “soil amendment” and “soil stabilizer” in soil science (Gilda Dell'Ambrogio and Wong, 2019), is commonly used to modify the unfavorable and damaged characteristics of soil.

What is polyacrylamide (PAM)?

Polyacrylamide (PAM) possesses unique characteristics, including high water solubility, elevated viscosity and effective flocculation capabilities. These properties make it valuable in various sectors like agriculture, wastewater treatment, enhanced oil recovery, and mineral processing industries, contributing to a continually expanding market.

Can polyacrylamide contribute to residual polymer formation?

Common methods for treating PAM are membrane filtration 25, thermal distillation 24, oxidation treatment 26, and biological treatments 27. However, addressing the challenge posed by PAM remains a pressing issue within the industry. Fig. 1: Polyacrylamide and its fragments may contribute to residual polymer formation.

Is polyaluminium chloride suitable for paper industry wastewater treatment?

In terms of the investigated paper industry wastewater, polyaluminium chloride appears to be most suitable for treatment of high COD concentration. However, in an economic evaluation of requirements for wastewater treatment, operating costs and associated saving were such that PAX was more favourable.
